HAROLD LEE HART, OF GALESIBURG, ILLINOIS.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed October 24, 1914. Serial No. 868,500.

To all whom it may concern:

Be it known that HAROLD L. HART, citizen of the United States, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to a non-refillable bottle, and more particularly to a bottle of this character in which the neck of the bottle is closed by means of a casing having a valve and a valve seat disposed therein, the valve being so positioned in the seat that when the bottle is inverted the valve will operate to permit the pouring out of the contents of the bottle, but when it is attempted to refill the bottle the valve will automatically seat and prevent such operation.

An object of the invention is to so construct the casing valve seat that the valve may be positioned in the seat and the seat within the casing with a minimum of time and labor. Y

Another object of the invention is to form a valve casing of two parts, one of the parts forming a valve seat, while the other of the parts form a means for limiting the movement of the valve, the forming of the valve casing in two sections serving to facilitate the positioning of the valve within the casing, as well as facilitating the insertion of the valve casing within the casing for the neck of the bottle.

With these and other objects in view the invention consists in the novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and claimed.

In the drawings; Figure 1 is a sectional view of a bottle neck showing the improved valve applied thereto in elevation. Fig. 2 is a view similar to Fig. 1 but showing the respective casings in section. Fig. 3 is a detailed, perspective, view of the casing for the neck of the bottle.

Referring to the drawings by numerals, 1 designates a bottle neck which is provided with an internally projecting annular flange 2.

A hollow casing 3 is disposed in the neck of the bottle and has an oifset portion 4: which is adapted to rest upon the upper face of the flange 2 to limit the downward movement of the casing.

Depending arms 5 are formed on the lower portion of the casingv 1 and'have tongues 6 struck therefrom which are adapted to spring outwardly and engage the under face of the flange 2 when the casing is inserted in the neck of the bottle to prevent the ready removal of the same, the lowermost portions of the arms 5 having projections 7 formed thereon, for a purpose which will subsequently appear.

valve casing comprising a lower portion 8, which forms a valve seat, and an upper portion 9 which serves as a limiting means for the valve, is positioned within the casing 3 and will be held within the casing after being sprung past the arms 5, by means of the projections 7 which engage the lower face of the portion 8 of the valve casmg.

A valve 10 is disposed in the opening 11 of the portion 8 of the valve casing, and is limited in its upward movement by means of a recessed stop portion 12 formed in the member 9.

By reference to the drawings it will be seen that when the bottle is inverted, the valve will rest in the stop 12, and the liquid will be free to pass outwardly through the opening 11 and the openings 13 formed in the member 9, and thence outwardly through openings 14 formed in the upper wall of the casing 3. It will also be noted that when the valve is seated and the bottle is in an upright position, the ready refilling of the bottle will be prevented.

From the foregoing description taken in connection with the accompanying drawings, it is thought that the construction and operation of the device will be clearly understood, and while I have herein shown and described one specific form of my invention, I do not wish to be limited thereto except for such limitation as the claim may impart.

I claim:

A bottle including a neck, an annular flange formed on and projecting into said neck, a casing arranged in said neck and seated on said flange, opposite arms depending from the under face of said casing, said arms being spaced from the periphery of.

said casing, and engaging the inner face of said flange, a valve casing, the lower extremities of said arms being bent inwardly for supporting said valve casing, flexible tongues struck from said arms, the free ends of said tongues engaging the under face of said flange for preventing the removal of with openings communicating with the insaid first mentioned casing, said valve casterior thereof. 10 ing tapering toward its upper end, the upper In testimony whereof I aflix my signature end of said valve casing abutting the under in presence of two witnesses.
